Device for manufacturing groove in large circular tube

Abstract

The invention provides a device for manufacturing a groove in a large circular tube. The device is provided with an annular supporting plate. The symmetrical positions at the two ends of the annular supporting plate in any diameter direction are provided with positioning devices in a clamped mode. The annular supporting plate is provided with four clamp slots. The four clamp slots jointly divide the annular supporting plate into four equal regions. Each clamp slot is formed in the radial direction of the annular supporting plate and internally provided with a threaded connection rod in a clamped mode, wherein the threaded connection rod is capable of moving along an opening of the corresponding clamp slot. The front end of each threaded connection rod is provided with a sliding block. The sliding blocks can slide in the corresponding clamp slots. Nuts are assembled to the threaded connection rods. The nuts can tightly connect the annular supporting plate and the threaded connection rods when screwed. The other end of each threaded connection rod is fixedly connected with a set of semi-automatic cutting equipment. The semi-automatic cutting equipment makes rolling contact with the circular tube to be machined. The device is simple in structure, free of moving the tube, safe and convenient to operate, low in energy consumption and capable of improving groove manufacturing efficiency, the production cycle is shortened, and enterprise efficiency is improved beneficially.

Description

technical field [0001] The invention relates to the technical field of steel structure production equipment, in particular to a large-scale circular pipe groove making device. Background technique [0002] In the butt joint process of round pipes in steel structures, in order to ensure penetration or improve the joint strength of workpieces and adjust the fusion ratio, some large-scale finished round pipes need to be cut or beveled. Because the diameter of the round pipe is large and easy to roll, it is necessary to cut Or the beveling is more difficult, and at the same time, in order to save the production cost, semi-automatic cutting equipment is usually used to cut the beveling of the project. Complete the pipe beveling work. [0003] Existing beveling of large-scale round pipes mostly uses special round pipe bevel cutting equipment or rotating pipes for cutting. The special equipment is expensive and increases the cost. It needs to consume more manpower, resources and ...

[0002] In the butt joint process of round pipes in steel structures, in order to ensure penetration or improve the joint strength of workpieces and adjust the fusion ratio, some large-scale finished round pipes need to be cut or beveled. Because the diameter of the round pipe is large and easy to roll, it is necessary to cut Or the beveling is more difficult, and at the same time, in order to save the production cost, semi-automatic cutting equipment is usually used to cut the beveling of the project. Complete the round pipe beveling work

[0003] Existing beveling of large-scale round pipes mostly uses special round pipe bevel cutting equipment or rotating pipes for cutting. The special equipment is expensive and increases the cost. It needs to consume more manpower, resources and time, which is not conducive to the improvement of enterprise benefits; the existing patent No. 201320215900.9 is the patent "curved plate bevel processing tooling", which installs a pipe cutting machine on the track of the round pipe column, cutting The device is connected to the rotating shaft through a movable joint, and the pipe cutting machine is magnetically adsorbed on the track of the circular pipe column. The main technical problem to be solved is the problem that the arc-shaped plate groove of the circular corbel needs to be polished after making; another application number For the 201320527615.0 patent "Cutting Auxiliary Device for Large Circular Pipe Cutting and Beveling", a height-adjustable cutting equipment rack is set up, and the cutting equipment is fixed in height and proximity to cooperate with large-scale circular pipe cutting and beveling. The positioning device is used to work, and the main technical problems to be solved are the large size deviation and poor quality of gas cutting grooves during manual cutting; these technologies have low work efficiency, heavy equipment or need to move large pipes, high energy consumption, which is not conducive to improving enterprise efficiency
